T 0 alt 'U/ZLOWL it may concern:

Be it known that 1, WILLIAM Grow, a citizen of the United States, residing at Independence, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Autoplows, of which the following is a specification.

My invention relates to auto gang plows, and one object of the invention is to provide a motor-driven plow wherein the plowheams forming part of the gang may be either simultaneously or independently raised or lowered.

Another object is to provide improved mechanism for removing the plow shares from working position, or for lowering them to such position, the act-ion of said mechanism being such as to facilitate either of said operations by inclining the shares upwardly or downwardly.

In order that the invention may be fully understood, reference will now be made to the accompanying drawings, in which:

Figure 1 is a side elevation of a gang plow constructed in accordance with the invention, the motor being omitted. Fig. 2 is a top plan View of the same, a portion of the platform being broken away and the motor omitted. Fig. 3 is an enlarged section on line HI.-IH of Fig. 2, showing one of the plows and its governing mechanism. at is a top view of the parts shown in Fig. 3, omitting the frame beam and showing bearings in section. Fig. is a detail view in section on line VV of Fig. 3. Fig. 6 is a detail view of a portion of Fig. 3, showing the wheel turned to a different position and omitting the part 18. F ig. 7 shows means for raising and lowering a plow independ ently of the others.

In F ig. 2, 1, designates the main frame, which is rhomboidal in plan and is preferably constructed of steel or iron beams, which are shown in section in several of the detail views. This frame is covered by a main platform72, and an extension platform is also provided for the'convenience of the operator, whose seat 4 is mounted thereon.

T he frame is supported by a rear traction wheel 5, a small front wheel 6 at the same side, and a front traction wheel 7 at the opposite side. signed to run in furrows while the third wheel runs on the land. The normal relative height of the wheels, when plowing, is shown on Fig. 1.

8 designates a plurality of plow beams of usual form, and each having a separate mechanism for raising and lowering relatively to the frame, said'mechanisms being operable simultaneously by a single lever as 9, or individually by separate levers 9".

Each plow beam is supported at its rear end by. a pair of inclined links 10, pivoted thereto at 13 and pivotally hung from a bearing 12 on the frame 1. Said links converge toward their lower ends to brace the plow beam against swaying laterally. At the side of the forward end of the plow beam is a ratchet-wheel 14, on a shaft 15, in a bearing 16 fixed to the frame 1. On this wheel is a wrist-pin 17 which passes through the plow-beam, and projects past same for engagement wit-h a spring dog 18. The ratchet-wheel, in the present instance has three teeth 19, two of which are opposite each other, and the third is halfway between the two. To prevent reverse rotation, a gravity dog 20 is provided, on a fixed pivot 21. Pivoted on the shaft 15 is a pawl-arm 22 that carries a pawl. 23, engaging the ratchet-teeth 19. The pawl-ari'n 22 has no connection with links 10 and hence can turn the ratchet-wheel a limited distance independently of said links, and thus initially ralse or lower the share point before the share is bodily raised or lowered.

Mounted in bearings 2:: on the underside of the frame 1 is a transverse rock-shaft 25, on which is fixed the hand-lever 9 provided with a latch and quadrant 26. Looselymounted on said shaft are a series of arms 27, one for each plow share, and in line with the respective. pmvl-alf1ns 92- Each arm 27 is connected to its pawlarm by a pullrod 28. I

All of thc-pawl-arms 27 except the one at the left side of the machine, are pro vided with the lovers 9. so that the plows may be op rated individually when the latches of said lovers are rel eased from their respectivenotched sectors 9*. Sectors 9 are fixed to shaft 25 t6 loch therewith and to normally look the arms 27 upon said shaft through the interinediacy of lovers 9 and their latches.

Each spring dog 18 is shaped as shown in Figs. 3 and 4 and is secured adjustablv to the adjacent hearing 16 with a ,bolt 29' and an adjusting screw 29, the former of which extends through a slot 29 in the dog and the latter through the upturned for- Ward end of the dog. Each spring dog 18 is formed with a shoulder 18 that stands in the path of the wrist-pin 17 and stops the same when the share 80 is in usual Working position, as shown'by full lines Fig. 3. The dog extends rearwardly as shown, then laterally as at 18", below the platform and passes up through the latter, terminating in a foot-plate 31.

Each plow share mechanism is provided with a spring dog of the construction described, see Fig.

The operation is as follows: N hen the lever 9 is moved to and fro with the proper stroke it actuates the arms 2-7, rods 28, pawlarms 22 and paivls 33, which latter drive the ratchet Wheels 1 and Wrist-pins 17. When the latter ascend they lift the front ends of the beams thereby tilting the shares 30 to or toward the position shown in dotted lines, Fig. 3. Further rotationof the ratchet-Wheels Will draw the beams for- Werdly, then downwardly, so it is apparent that said ratchet-Wheels turn in the same direction both to and lower the shares. iZefore raising them from the position of full lines in Fig. 3, it will of course be necessary to disengage the spring dogs 18, which the operator does by depressing the pedals 31. The function of the said dogs in connection with ratchet-Wheels l-i isto hold the shares down to their work. Vdhen it is desired to raise the shares out of the earth, the spring dogs are disengaged from vvristpins 1'? nd the beams are moved to the dotted line positon, Fig. 3, therebyupwardly inclining the shares in front. As the whole machine is moving forward, this upward inclination of the share points Will itself lift the shares and n'iold-boards, While the links 1.0 will swing forwardly as the beams are brought to the position shown in. dotted lines. Th is very advantageous over the known devices for lifting the shares, because letter the weight of the parts must with the V be lifted out of the ground by the operator, Whereas with my device the operator has only to change the angle which the shares are suspended, and the forward motion of the plow effects the ting. A similar advantage attaches to the reverse movement 2'. 0., when the shares are about to be sunl; into the ground to start plowin" the n p bincd control of the )QJl by links if) and n T LAM the Wrist-pin ll Wi l cause the point of the share to descend before the rear descends.

thus causing the s c to force itself into .1 the ground when the Ward.

The iuechanisn'i just described is not designed for holding the shares in internuadiate Working positions, but. means have been provided for that purpose, operative by shifting the main frame up and down at the forward end thereof. Said means embodies I Wheel 6,

a lever 38 for adjusting the right side of the frame up and down, and a leverdS to adjust the left side of said frame up and down. By thus raising and lowering the front end of the main frame the shares may be adjusted to any desired depth in the soil, and after the frame has been adjusted as desired, it may be locked from accidental movement by sectors 39 and 50, adapted to be engaged, respectively, by the levers 3S and 48.

To start plovvin on unfurroived land. the operator should 1' lse the small front who i 6 and the front traction Wheel '1' shares are at a required depth. its as there is a furrow for the front trovv eel to run in, it will be lowered to the le 'el of the plow shares.
